I heard about this on NPR and love the idea of it. It's a free network of websites to seek and post employment ads based on your area or city. Basically you can type in SanFrancisco.jobs (or whatever city you're in) or education.jobs (or whatever field you're in) or SanFranciscoeducation.jobs (city and field) to find work that might be relevant to your field, location or both! Brilllliant.
